The M37x enhances the performance capabilities of Infiniti's midsize luxury sedan with all-wheel drive. Powered by a 3.7-liter V6, the M37x has estimated fuel economy of 17 mpg city and 24 mpg highway -- only one mile per gallon less than the lighter rear-wheel drive M37.

The all-wheel drive model is also equipped with Infiniti Drive Mode Selector, an integrated control system that allows drivers to select from four driving modes: Standard, Eco, Sport and Snow.
